Bio-based foam adsorbents for air purification – step 1

Air filters are used in air purification systems to remove harmful pollutants that can cause negative health effects and damage sensitive objects. The current solution for air purification is to use air filters made from activated carbon, which has significant environmental effects. The goal of the project is to demonstrate that commercially attractive air filters can be produced using cellulose-based materials and a production technique with low environmental impact.
